I've recently tried to use CentOS 5.3 with a 2.6.31 kernel - along with 
an earlier RHEL5/CentOS5 nfs-utils from before FS-Cache was disabled in 
  RHEL5/CentOS5 ... unfortunately, the patches Redhat made to 'their' 
RHEL5 nfs-utils package for the 'fsc' mount option don't work with 
vanilla 2.6.30 or 2.6.31 kernels ... I believe the 'fsc' mount option 
gets interpreted as 'nordirplus' by these kernels

It's probably best to build a more recent (non-Redhat) version of 
nfs-utils from <http://sourceforge.net/projects/nfs/> - you only need 
the /sbin/mount.nfs binary for it to work.

I also had to add a couple of kernel patches (found on this list) to get 
things working, although I haven't used FS-cache in anger yet.
